Hedge-fund playboy Marc Leder — made famous by The Post’s Page Six column for his sexually charged Bridgehampton parties last year — was the host of the fund-raiser where Mitt Romney was recorded saying 47 percent of Americans are “dependent on government.”

Leder, 50, a hedge-fund CEO, is a big booster of the Republican presidential nominee and defender of Romney’s role at Bain Capital.

But the two seem to share quite different family values.

Leder, who is divorced and reputed to be worth $400 million, had weekly Friday- and Saturday-night parties at a sprawling beachfront mansion he rented for $500,000 just for the month of July 2011. He attracted guests such as Russell Simmons and Simmons’ ex-wife, Kimora Lee.

But nothing compared with the final bash July 30, as Page Six reported:

“Guests cavorted nude in the pool and performed sex acts, scantily dressed Russians danced on platforms and men twirled lit torches to a booming techno beat.”

Witnesses said a man and woman stripped, jumped into the pool and later performed sex acts on a lounge chair before stunned fellow partygoers.

A friend said Leder “went wild” after his 22-year marriage collapsed in 2009 and his ex-wife admitted to cheating on him with her 23-year-old tennis coach.

Leder, the co-CEO of Sun Capital Partners, was apparently more sedate when he hosted the $50,000-a-plate fund-raiser in May at his Boca Raton, Fla., home for Romney.

But he may not be done. No invitations have gone out yet, but there is talk of Leder hosting another fund-raiser, with both Romney and running mate Paul Ryan, at the Boca Raton home.
